The STMicroelectronics M24128-BRMN6TP is a 128 Kbit (16 KB, 16K x 8) serial EEPROM with an I2C two-wire interface, supplied in an 8-pin narrow-body SOIC on 2, 500-piece tape and reel. It operates from 1.8 V to 5.5 V, so it works directly on 2.5 V, 3.3 V, and 5 V systems, and runs the bus at up to 400 k Hz with a 900 ns access time. The M24128-BRMN6TP is rated -40°C to 85°C, is lead free and RoHS compliant, and carries an MSL 1 moisture sensitivity rating.

This part holds the small persistent data blocks a board needs across power cycles: calibration values, board and module identification, network or user configuration, and fault and runtime logs. EEPROM writes at byte granularity, so firmware can update one parameter without erasing a page, which is why it is still preferred over flash for settings storage. The SOIC-8 footprint is easy to hand-rework and probe, making it common on industrial boards, backplanes, and modules that get serviced in the field. Typical buyers are industrial automation, appliance, medical, metering, and communications OEMs and their contract manufacturers.
